The activities of the department of Laser Technologies includes Nanophotonics, Laser Science and Applications, the Development of Optical Component of Lasers, the Design of new Fiber and solid-state Lasers and their Application for Precise Material Processing. Our research focuses on the development of complex dielectric optical coatings, high-pulse energy fiber lasers, and amplifiers. Nonlinear interactions by generating harmonics or combining laser beams are used to increase laser power. High-average power solid state lasers excited by diodes with synchronized modes or modulated quality of solid-state lasers are developed for specialized technological applications. New interactions between laser radiation and materials are looking in order to develop and install laser microfabrication technologies for the modification of metals, semiconductors, dielectrics, as well as for the modification of thin layers of solar cells. Research is also being carried out by modeling, developing and characterizing nanophotonic structures, waveguides, and metamaterials for light control.
